GENEVA — Growing tensions over Ukraine have raised the specter of another slowdown in the European auto market, just as carmakers were beginning to count on a modest recovery from a six-year contraction.

Russia’s intervention in Ukraine has raised the possibility of sanctions against the country, which has been a key growth market for recession-battered European automakers.

At the Geneva International Motor Show on Tuesday, executives cast a wary eye toward the crisis.

“There is not a single doubt in my mind that if the situation in Russia and the Ukraine remains as tight as it is, or if it worsens from where we are, that it will dampen demand in western Europe,” said Fiat Chrysler Automobiles CEO Sergio Marchionne.

“We believe that now is the right time for a new model,” said Stephan Winkelman, head of the Santa’Agata Bolognese, Italy-based carmaker. “We are very proud of this car. I don’t see any competitor.”

Ferrari may beg to differ. The Fiat SpA unit lifted a red shroud from the 560-horsepower California T, which accelerates to 100 kilometers (62 miles) per hour in 3.6 seconds. Reflecting the effort to improve efficiency even for elite racers, Ferrari boasted that it reduced the model’s emissions by 20 percent versus the $198,190 predecessor.

“I like competition, particularly when we win the competition,” Ferrari Chairman Luca Cordero Di Montezemolo said in an interview.

Sales in Europe of high-end sports cars will likely rise this year for the first time since 2010, IHS Automotive estimates.

Global deliveries may increase to 15,200 in 2018, 14 percent above 2014 sales, helped by the Huracan, California T and other new models in the pipeline, IHS forecasts.

“Supercar-makers are heavily investing to keep up the pace with a growing market,” said Gian Primo Quagliano, head of automotive-research company CSP in Bologna.

Lamborghini had more than 1,000 orders for the Huracan, even before the media day Monday.

British sports-car maker McLaren unveiled coupe and topless versions of the new 650S, which is promoted as a supercar.

Andy Goss, group sales director at Jaguar Land Rover, said global demand for upscale vehicles “still looks very strong and there’s no sign of that dissipating. We’ve got more sales opportunities than supply.”
